 anoden wird sofort nach Unterbrechung des Glühstromkreises der Hilfsanodenstromkreis geschlossen, der sodann auch unterbrochen wird. 



   In den Fig. 1 und 2 sind die Widerstände in dem Glühkathoden-, Anoden- und Hilfsanodenstromkreis teilweise dieselben. Es ist einleuchtend, dass diese Widerstände auch geordnet angebracht werden können. 



    PATENT-ANSPRÜCHE :  
1. Schaltung zum Betrieb einer gasgefüllten   Glühkathodenentladungsrohre   mit Gleichstrom, bei der die Entladungsröhre und ihre Glühkathode aus derselben   Spannungsquelle   gespeist werden, gekennzeichnet durch eine Drosselspule in dem Stromkreis der Entladungsröhre.

 anode, the auxiliary anode circuit is closed immediately after the glow circuit is interrupted, which is then also interrupted.



   In Figs. 1 and 2, the resistances in the hot cathode, anode and auxiliary anode circuits are partially the same. It is obvious that these resistors can also be placed in an orderly manner.



    PATENT CLAIMS:
1. Circuit for operating a gas-filled hot cathode discharge tube with direct current, in which the discharge tube and its hot cathode are fed from the same voltage source, characterized by a choke coil in the circuit of the discharge tube.

Claims (1)

2. Schaltung nach Anspruch 1, dadurch gekennzeichnet, dass Anschlüsse für eine oder mehrere Hilfsanoden der Entladungsröhre vorhanden sind. 2. Circuit according to claim 1, characterized in that connections for one or more auxiliary anodes of the discharge tube are present. 3. Verfahren zum Betrieb einer elektrischen Entladungsröhre in einer Schaltung nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass, während an den Elektroden Spannung liegt, der Glühstrom unterbrochen wird. EMI2.1 3. A method for operating an electrical discharge tube in a circuit according to claim 1 or 2, characterized in that, while voltage is applied to the electrodes, the glow current is interrupted. EMI2.1
